Effect of Kemzyme - Bentonite Co-supplementation on Cecal Fermentation and Metabolic Pattern in Rabbit

Abstract

With the objective of improving the impact of multi-enzymes feed additives on cecal fermentation pattern and rabbit metabolism, sodium bentonite was co-supplemented with "Kemzyme", a multi-enzyme blend of Kemin Agrifoods Europe. Co-supplementation decreased cecal pH value, increased total VFAs concentration, increased propionate at the expence of acetate and butyrate, increased fermentation efficieny and VFAs utilization. Additionally, co-supplementation increased serum glucose concentration and decreased serum triglycerides and cholesterol concentrations. Cecal ammonia nitrogen and serum urea concentration were also decreased by co-supplementation while no change was recorded in serum total proteins concentration. The study therefore, suggested that, coupling bentonite to multi-enzyme feed additives could improve the impact of such enzymes on cecal fermentation pattern and rabbit metablism.

Influence of Dietary Supplementation of Coated Sodium Butyrate and/or Synbiotic on Growth Performances, Caecal Fermentation, Intestinal Morphometry and Metabolic Profile of Growing Rabbits

“…Caecal content samples were collected at the end of the experimental period post slaughtering for determination of caecal fermentation pattern namely, pH, total short chain fatty acids (Eadie et al, 1967), individual volatile fatty acids (Samuel et al, 1997) and ammonia concentration (Chaney & Marbach, 1962;Abdl-Rahman et al, 2010).…”

Wheat silage partially replacing oaten hay exhibited greater feed efficiency and fibre digestion despite low feed intake by feedlot lambs

“… 1 Four rations with wheat silage replacing 0% (WS0), 36% (WS36), 64% (WS64), and 100% (WS100) of oaten hay (dry matter in forage). 2 NGR = (acetate + 2 × butyrate + valerate)/(propionate + valerate) ( Abdl-Rahman et al., 2010 ). 3 Fermentation efficiency = (0.622 × acetate + 1.092 × propionate + 1.56 × butyrate)/(acetate + propionate + 2 × butyrate) ( Abdl-Rahman et al., 2010 ).…”
